+GIT v1.6.1 Release Notes
+========================
+
+Updates since v1.6.0
+--------------------
+
+When some commands (e.g. "git log", "git diff") spawn pager internally, we
+used to make the pager the parent process of the git command that produces
+output.  This meant that the exit status of the whole thing comes from the
+pager, not the underlying git command.  We swapped the order of the
+processes around and you will see the exit code from the command from now
+on.
+
+(subsystems)
+
+* gitk can call out to git-gui to view "git blame" output; git-gui in turn
+  can run gitk from its blame view.
+
+(portability)
+
+* ...
+
+(documentation)
+
+* ...
+
+(performance)
+
+* The underlying diff machinery to produce textual output has been
+  optimized, which would result in faster "git blame" processing.
+
+* Most of the test scripts (but not the ones that try to run servers)
+  can be run in parallel.
+
+* Bash completion of refnames in a repository with massive number of
+  refs has been optimized.
+
+(usability, bells and whistles)
+
+* When you mistype a command name, git helpfully suggests what it guesses
+  you might have meant to say.  help.autocorrect configuration can be set
+  to a non-zero value to accept the suggestion when git can uniquely
+  guess.
+
+* "git bisect" is careful about a user mistake and suggests testing of
+  merge base first when good is not a strict ancestor of bad.
+
+* "git checkout --track origin/hack" used to be a syntax error.  It now
+  DWIMs to create a corresponding local branch "hack", i.e. acts as if you
+  said "git checkout --track -b hack origin/hack".
+
+* "git cherry-pick" can also utilize rerere for conflict resolution.
+
+* "git commit --author=$name" can look up author name from existing
+  commits.
+
+* "git count-objects" reports the on-disk footprint for packfiles and
+  their corresponding idx files.
+
+* "git daemon" learned --max-connections=<count> option.
+
+* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
+  configuration option.
+
+* "git diff" learned to put more sensible hunk headers for Python and
+  HTML contents.
+
+* "git diff" learned to vary the a/ vs b/ prefix depending on what are
+  being compared, controlled by diff.mnemonicprefix configuration.
+
+* "git for-each-ref" learned "refname:short" token that gives an
+  unambiguously abbreviated refname.
+
+* "git help" learned to use GIT_MAN_VIEWER environment variable before
+  using "man" program.
+
+* "git imap-send" can optionally talk SSL.
+
+* "git index-pack" is more careful against disk corruption while
+  completing a thin pack.
+
+* "git log --check" and "git log --exit-code" passes their underlying diff
+  status with their exit status code.
+
+* "git log" learned --simplify-merges, a milder variant of --full-history;
+  "gitk --simplify-merges" is easier to view than with --full-history.
+
+* "git log --pretty=format:" learned "%d" format element that inserts
+  names of tags that point at the commit.
+
+* "git merge --squash" and "git merge --no-ff" into an unborn branch are
+  noticed as user errors.
+
+* "git merge -s $strategy" can use a custom built strategy if you have a
+  command "git-merge-$strategy" on your $PATH.
+
+* "git reflog expire branch" can be used in place of "git reflog expire
+  refs/heads/branch".
+
+* "git submodule foreach" subcommand allows you to iterate over checked
+  out submodules.
+
+* "git submodule sync" subcommands allows you to update the origin URL
+  recorded in submodule directories from the toplevel .gitmodules file.
+
+(internal)
+
+* "git hash-object" learned to lie about the path being hashed, so that
+  correct gitattributes processing can be done while hashing contents
+  stored in a temporary file.
+
+Fixes since v1.6.0
+------------------
+
+All of the fixes in v1.6.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+* "git add" and "git update-index" incorrectly allowed adding S/F when S
+  is a tracked symlink that points at a directory D that has a path F in
+  it (we still need to fix a similar nonsense when S is a submodule and F
+  is a path in it).
+
+* "git diff --stdin" used to take two trees on a line and compared them,
+  but we dropped support for such a use case long time ago.  This has
+  been resurrected.
+
+* "git filter-branch" failed to rewrite a tag name with slashes in it.
+
+* "git push --tags --all $there" failed with generic usage message without
+  telling saying these two options are incompatible.
+
+* "git log --author/--committer" match used to potentially match the
+  timestamp part, exposing internal implementation detail.  Also these did
+  not work with --fixed-strings match at all.

 DESCRIPTION
 -----------
 
-'git-merge-base' finds as good a common ancestor as possible between
-the two commits. That is, given two commits A and B, `git merge-base A
-B` will output a commit which is reachable from both A and B through
-the parent relationship.
+'git-merge-base' finds best common ancestor(s) between two commits to use
+in a three-way merge.  One common ancestor is 'better' than another common
+ancestor if the latter is an ancestor of the former.  A common ancestor
+that does not have any better common ancestor than it is a 'best common
+ancestor', i.e. a 'merge base'.  Note that there can be more than one
+merge bases between two commits.
 
-Given a selection of equally good common ancestors it should not be
-relied on to decide in any particular way.
-
-The 'git-merge-base' algorithm is still in flux - use the source...
+Among the two commits to compute their merge bases, one is specified by
+the first commit argument on the command line; the other commit is a
+(possibly hypothetical) commit that is a merge across all the remaining
+commits on the command line.  As the most common special case, giving only
+two commits from the command line means computing the merge base between
+the given two commits.
 
 OPTIONS
 -------
 --all::
-       Output all common ancestors for the two commits instead of
-       just one.
+       Output all merge bases for the commits, instead of just one.
+
+DISCUSSION
+----------
+
+Given two commits 'A' and 'B', `git merge-base A B` will output a commit
+which is reachable from both 'A' and 'B' through the parent relationship.
+
+For example, with this topology:
+
+                o---o---o---B
+               /
+       ---o---1---o---o---o---A
+
+the merge base between 'A' and 'B' is '1'.
+
+Given three commits 'A', 'B' and 'C', `git merge-base A B C` will compute the
+merge base between 'A' and an hypothetical commit 'M', which is a merge
+between 'B' and 'C'.  For example, with this topology:
+
+              o---o---o---o---C
+             /
+            /   o---o---o---B
+           /   /
+       ---2---1---o---o---o---A
+
+the result of `git merge-base A B C` is '1'.  This is because the
+equivalent topology with a merge commit 'M' between 'B' and 'C' is:
+
+
+              o---o---o---o---o
+             /                 \
+            /   o---o---o---o---M
+           /   /
+       ---2---1---o---o---o---A
+
+and the result of `git merge-base A M` is '1'.  Commit '2' is also a
+common ancestor between 'A' and 'M', but '1' is a better common ancestor,
+because '2' is an ancestor of '1'.  Hence, '2' is not a merge base.
+
+When the history involves criss-cross merges, there can be more than one
+'best' common ancestors between two commits.  For example, with this
+topology:
+
+       ---1---o---A
+          \ /
+           X
+          / \
+       ---2---o---o---B
+
+both '1' and '2' are merge-base of A and B.  Neither one is better than
+the other (both are 'best' merge base).  When `--all` option is not given,
+it is unspecified which best one is output.

+HOW CONFLICTS ARE PRESENTED
+---------------------------
+
+During a merge, the working tree files are updated to reflect the result
+of the merge.  Among the changes made to the common ancestor's version,
+non-overlapping ones (that is, you changed an area of the file while the
+other side left that area intact, or vice versa) are incorporated in the
+final result verbatim.  When both sides made changes to the same area,
+however, git cannot randomly pick one side over the other, and asks you to
+resolve it by leaving what both sides did to that area.
+
+By default, git uses the same style as that is used by "merge" program
+from the RCS suite to present such a conflicted hunk, like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+The area a pair of conflicting changes happened is marked with markers
+"`<<<<<<<`", "`=======`", and "`>>>>>>>`".  The part before the "`=======`"
+is typically your side, and the part after it is typically their side.
+
+The default format does not show what the original said in the conflicted
+area.  You cannot tell how many lines are deleted and replaced with the
+Barbie's remark by your side.  The only thing you can tell is that your
+side wants to say it is hard and you'd prefer to go shopping, while the
+other side wants to claim it is easy.
+
+An alternative style can be used by setting the "merge.conflictstyle"
+configuration variable to "diff3".  In "diff3" style, the above conflict
+may look like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.

+
+In addition to the "`<<<<<<<`", "`=======`", and "`>>>>>>>`" markers, it uses
+another "`|||||||`" marker that is followed by the original text.  You can
+tell that the original just stated a fact, and your side simply gave in to

-Abstract: In this article, Linus demonstrates how a broken commit
- in a sequence of commits can be removed by rewinding the head and
- reapplying selected changes.
-

-
-> That's correct. Same things apply: you can move a patch over, and create a

-> immutable.
-
-Let me clarify.
-
-You can entirely _drop_ old branches, so commits may be immutable, but
-nothing forces you to keep them. Of course, when you drop a commit, you'll
-always end up dropping all the commits that depended on it, and if you
-actually got somebody else to pull that commit you can't drop it from
-_their_ repository, but undoing things is not impossible.
-
-For example, let's say that you've made a mess of things: you've committed
-three commits "old->a->b->c", and you notice that "a" was broken, but you
-want to save "b" and "c". What you can do is
-
-       # Create a branch "broken" that is the current code
-       # for reference
-       git branch broken
-
-       # Reset the main branch to three parents back: this
-       # effectively undoes the three top commits
-       git reset HEAD^^^

-       # going on
-       gitk --all
-
-       # Re-apply the two top ones from "broken"
-       #
-       # First "parent of broken" (aka b):
-       git-diff-tree -p broken^ | git-apply --index
-       git commit --reedit=broken^
-
-       # Then "top of broken" (aka c):
-       git-diff-tree -p broken | git-apply --index
-       git commit --reedit=broken
-
-and you've now re-applied (and possibly edited the comments) the two
-commits b/c, and commit "a" is basically gone (it still exists in the
-"broken" branch, of course).
-
-Finally, check out the end result again:
-
-       # Look at the new commit history
-       gitk --all
-
-to see that everything looks sensible.
-
-And then, you can just remove the broken branch if you decide you really
-don't want it:
-
-       # remove 'broken' branch
-       git branch -d broken
-
-       # Prune old objects if you're really really sure
-       git prune
-

-To syntax highlight git's commit messages, you need to:
-  1. Copy syntax/gitcommit.vim to vim's syntax directory:
-     $ mkdir -p $HOME/.vim/syntax
-     $ cp syntax/gitcommit.vim $HOME/.vim/syntax
-  2. Auto-detect the editing of git commit files:
-     $ cat >>$HOME/.vimrc <<'EOF'
-     autocmd BufNewFile,BufRead COMMIT_EDITMSG set filetype=gitcommit
-     EOF
+Syntax highlighting for git commit messages, config files, etc. is
+included with the vim distribution as of vim 7.2, and should work
+automatically.
+
+If you have an older version of vim, you can get the latest syntax
+files from the vim project:
+
+  http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/git.vim
+  http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitcommit.vim

+
+  1. Copy these files to vim's syntax directory $HOME/.vim/syntax
